MIL-STD-209 Lifting And Tiedown ProvisionsThis standard establishes dimensional limits, design considerations, positioning requirements, and strength requirements for lifting to include helicopter sling load HSL and tiedown provisions for lifting or tying down tanks and other tracked vehicles, tactical wheeled vehicles, helicopters, and other military equipment shipped assembled or disassembled in unboxed or uncrated condition, and for restraining cargo or accessories to such equipment. The lifting and tiedown requirements in this standard are necessary to permit compatibility between military equipment and the transportation systems used for deployments.

Elevation view of equipment when lifted with equal length slings

H = H + H + K

a f t

TAN (�) = Ht/ha

t = TAN(�)(ha) = TAN(3.80)(58.2) = 3.9 inches

= 24 + 3.9 + 125.2 = 153.1 inches = 12.8 feet

This is less 24 feet and therefore meets the apex height requirements of paragraph 5.1.2.i.
